Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573712, here are decompositions:

73 + 31573639 = 31573712
151 + 31573561 = 31573712
199 + 31573513 = 31573712
211 + 31573501 = 31573712
349 + 31573363 = 31573712
433 + 31573279 = 31573712
523 + 31573189 = 31573712
601 + 31573111 = 31573712

Showing the first eight; more decompositions exist.
